Description

The invention of production, in the development used in the method "wall

The purpose of the invention of driving by cleaning the receiving window from the destroyed soil and to facilitate the launch of airlift.

In FIG. 1 shows a trencher, general view; in FIG. 2 - node Ί in FIG. one.

The trencher includes a base machine 1, a working body .2, mounted with the ability to move along the rails of a vertical rack 3, at the same time acting as an airlift elevator, a supporting frame 4 with a mechanism 5 for moving the working body 2 along the trench. In the lower part of the vertical strut 3 under the intake window 6 there is a sealed accumulator 7, inside of which a pneumatic elastic shock absorber is placed 8. The sealed accumulator 7 is equipped with an outlet pipe 9 on which an automatic valve 10 is fixed. The sealed accumulator 7 is hydraulically connected to a high-pressure supercharger 11 for water supply .

The trencher works as follows.

The working body 2, suspended on the rope of the base machine 1, descending along the guides of the vertical rack 3, develops a trench. At the same time separated from

It relates to particular trenches, the construction of structures in the ground. "

increased production 10 pieces of soil fall to the bottom of the trench, from where they enter the vertical rack 3 through the intake window 6 and are transported to the surface using the airlift elevator. After developing the walls of the trench to the design depth, the working body 2 together with the vertical strut 3 using the movement mechanism 5 moves in the support frame 4 by a distance equal to the thickness of the chips developed by the working body 2 of the soil. When clogging the intake window 6 with soil or the formation of a sediment of increased density at the bottom of the trench due to a long interruption in operation, water is supplied to the sealed drive 7 by a high-pressure supercharger 11, under the pressure of which the pneumatic elastic shock absorber 8, filled with air, is compressed. When the calculated pressure in the sealed drive 7 reaches the automatic valve 9, and the water in the sealed drive 7 _? under the action of a pneumatic elastic shock absorber 8 through the outlet pipe 9 is ejected under pressure in the direction of the intake window 6 and cleans it of soil. After the ejection of part of the water and the decrease in pressure in the sealed accumulator 7, the automatic valve 10 closes. The incoming water is repeated.

from a high-pressure supercharger 11 again increases the pressure in the hermetic accumulator 7 to the calculated one, and the cycle
